Explanation:

Question 1

An event in probability is defined as the chance of something happening. Option a is incorrect as probability is a measure, not an event. Option b refers to a literal event to attend, not in a probability context. Option d is incorrect as an event is not the origin of probability. So the correct option is c.

Step1: Recall die outcomes

A 6 - sided die has faces numbered 1, 2, 3, 4, 5, 6.

Step2: Count outcomes

The number of possible outcomes is the number of distinct faces, which is 6.

Step1: Identify even numbers on die

The even numbers on a 6 - sided die are 2, 4, 6. So there are 3 favorable outcomes.

Step2: Total outcomes

A 6 - sided die has 6 total outcomes.

Step3: Calculate probability

Probability $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{3}{6}=\frac{1}{2}$.

Answer:

c. Chance of something happening
